The Boost V2 Docs are under active development and will be subject to changes.
Boost components aren’t instantiated traditionally, with parameters supplied to the contract’s constructor on deployment. Instead, to ensure each Boost component is compliant with a registered base implementation, and save on gas, components are either cloned from a deployed base contract and initialized ahead of time through registry before being referenced in Boost creation, or, for some components, initialized at time of Boost creation.
Incentives are not re-usable between multiple Boosts, and cannot be initialized by the registry.

​
What is a base implementation?

A base implementation is any deployed contract registered with the registry, thus valid for use with Boost creation, that satisfies the interfaces for either Action, AllowList, Budget, Incentive or Validator. For example, ManagedBudget is a base implementation that satisfies the Budget interface.

​
API

​
initialize

Deploys and initializes a new instance of a registered component’s base implementation and returns the component with its address attached. 
const budget = await registry.initialize('MyNewBudget', core.ManagedBudget({
  owner: '0xME',
  authorized: ['0xME', core.assertValidAddress()],
  roles: [Roles.ADMIN, Roles.MANAGER]
}))
Clones are uniquely identified by hashing the component’s type, base address, your address, and name. For example, you cannot initialize two ManagedBudget’s with the same displayName

​
Parameters

​
displayName
string
required
A display name for the new instance. Must be unique per account and base implementation.
​
target
AllowList | Budget | Action
required
An instance of the component you’d like to initialize.
​
parameters
Omit<wagmi.WriteContractParameters, 'address' | 'args' | 'functionName' | 'abi'>
Optional parameters to pass to the underlying writeContract method. Checkout wagmi’s documentation for more information. address, args, functionName, abi are handled for you under the hood.

​
Returns

​
target
Promise<AllowList | Budget | Action>
required
Returns the target parameter with its deployed address attached.
const budget = await registry.initialize('MyNewBudget', ...)
isAddress(budget.assertValidAddress()) // true
You can then reuse it during Boost creation.
await core.createBoost({ budget, ...otherComponents })
// or you can re-use with its address if you already have it
await core.createBoost({ budget: core.ManagedBudget(budget.assertValidAddress()), ...otherComponents })
